0805YD225KAT2A

The AVX 0805YD225KAT2A is a multilayer ceramic capacitor (MLCC) in the widely used 0805 surface-mount package. This component is designed for general-purpose decoupling, filtering, and coupling applications across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive systems. Multilayer ceramic capacitors like this model are among the most common passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. The 0805 package measures 2.0 mm by 1.25 mm, making it suitable for high-density circuit board layouts while remaining large enough to handle with standard automated assembly equipment. This size has become a industry standard, ensuring broad compatibility with design tools and manufacturing processes. The "YD" designation in the part number indicates this capacitor belongs to AVX's Y5V dielectric class, which is characterized by broad capacitance tolerance and stability across temperature and voltage ranges. Y5V dielectrics are best suited for non-critical filtering and decoupling roles where exact capacitance values are less critical than the need for stable performance and cost efficiency. Engineers typically specify Y5V ceramics for bulk decoupling near power supplies, high-frequency noise filtering, and general AC coupling applications. The 225 portion of the part number indicates the capacitance value, which follows standard EIA coding where two digits represent significant figures and one digit represents the multiplier in picofarads. This capacitance range is common for power supply decoupling on digital logic circuits and general filtering applications. Engineers choose the 0805YD225KAT2A over alternatives for several practical reasons. The 0805 package offers an optimal balance between board space savings and ease of handling and repair compared to smaller packages like 0603 or 0402. The Y5V dielectric provides acceptable performance at a lower cost than higher-stability options like X7R or C0G, making it economical for applications where tight capacitance tolerance is unnecessary. Additionally, AVX's manufacturing consistency and broad distribution of this part number ensure reliable supply chains and compatibility across multiple production batches. This capacitor is suitable for operating in standard commercial temperature ranges typical of most industrial and consumer electronics. It performs well in typical PCB assembly processes and is compatible with lead-free soldering requirements now standard across most industries.
